photovoltaic module is the most significant renewable energy technology as it
involves direct conversion of solar radiation into electricity. Several solar
cells are connected in series/parallel configuration to make it module in order
to obtain desired voltage and current. In photovoltaic effect, Photons give
their energy to electrons based on the conservation of momentum and energy principals.
The liberated electrons can move across the crystal. The experiment was carried
out to evaluate the performance of solar module under different condition using
solar photovoltaic test kit procured from IIT, Mumbai. The poly crystalline
module of 10 watt was
tested for two modes (i) manual tracking of module to follow the sun from east
to west (ii) Fixed orientation. For both condition the angle of inclination was
kept constant at Latitude +100 i.e. 34019’. The result
revealed that manually tracking of module recorded maximum power (10.23 W) even
under moderately low solar insolation of 1107 W/m2as compared to
module under fixed mode condition.
